Degradation of Small Simple and Large Complex Lunar Craters: Not a Simple Scale-dependence

We simulated the surface evolution for a pre-Nectarian surface unit and found that relative to their size, large complex craters are less destructive to the surrounding terrain than small simple craters.

The data is structured as follows:

01_CTEM_Outputs
- .dat files in which the craters from the simulations are stored
- Python script to convert the .dat files to shapefiles

02_Shapefiles_From_CTEM_Outputs
- Shapefiles in which the craters from the simulations are stored
- Shapefile of the surrounding area (created manually)

03_CSFD_Measurements
- A modified version of CSFD Tools to conduct Cartesian crater size-frequency distribution measurements
- .scc files which contain the results from the Traditional Crater Counting and Non-sparseness Correction techniques (for further analysis in Craterstats)

04_Crater_Statistics
- .stat files which contain crater size-frequency distribution statistics (obtained from the Craterstats software)

05_Crater_Equilibrium
- simplified .stat files which contain cumulative number density information
- Python script to fit a power law function to the simplified .stat files

06_Geometric_Saturation_Levels
- .stat files which contain crater size-frequency distribution statistics (obtained from the Craterstats software)
- Python script to calculate geometric saturation levels from .stat files
- .txt files containing geometric satration levels

本研究对前酒海纪（pre-Nectarian）地表单元的表面演化过程进行了数值模拟，结果发现：相较于自身尺寸，大型复杂撞击坑对周边地形的破坏程度要小于小型简单撞击坑。

本数据集的结构如下：
01_CTEM_Outputs
- 存储模拟所得撞击坑数据的.dat格式文件
- 用于将.dat格式文件转换为形状文件（Shapefile）的Python脚本
02_Shapefiles_From_CTEM_Outputs
- 存储模拟所得撞击坑数据的形状文件（Shapefile）
- 手动创建的研究区域周边形状文件
03_CSFD_Measurements
- 经过修改的CSFD工具版本，用于开展笛卡尔坐标系下的撞击坑尺寸-频率分布（Crater Size-Frequency Distribution，简称CSFD）测量
- 存储传统撞击坑计数与非稀疏校正技术分析结果的.scc格式文件（可用于Craterstats软件中的后续分析）
04_Crater_Statistics
- 存储撞击坑尺寸-频率分布统计数据的.stat格式文件（由Craterstats软件生成）
05_Crater_Equilibrium
- 简化版.stat格式文件，包含累积数密度信息
- 用于将幂律函数拟合至简化版.stat格式文件的Python脚本
06_Geometric_Saturation_Levels
- 存储撞击坑尺寸-频率分布统计数据的.stat格式文件（由Craterstats软件生成）
- 用于从.stat格式文件中计算几何饱和水平的Python脚本
- 存储几何饱和水平数据的.txt格式文件
